Be it known that'CnL C. Rio'rrn, late a` citizen of the United States, did invent certain new and useful Improvements in Va- .'porizers, of which the following is a full, clear, and exact description. Q Y

My invention relates, to improvements u vapcrlzers for internall combustion engines.

' leading to the engine, lnot shown.

- Theobject visfto provide means whereby 'a gas and'air maybe provided' at all times proportional'to the speedand worin` of the enginewith which thedevice is connected.

In the accompanying drawings, Figure 1 is a plan View of my improved vaporizer; Fig. 2'is, in the main, a vertical section, certain parts being shown in elevation. Fig. 3

is yatrend.eletnition of! Fig. 1,-1ooking from ri t` to left; Fig.. 4 is a. sectional view ita enl substantially on'the planeof the'line w-w of Fig. 2, certain lparts being shown in elevation. f .f

l represents the air inlet pipe which may be screened in the usual manner.

2-2 are nozzles arranged' inthe path of air entering through inlet 1. These nozzles are suppliedwith fuel from any suitable source, for example,l fromf the fuel tank 3, which in turn `gets its supply from any suit- 'able reservoir, noti shown. f

4 represents the mixture outlet. pipe constituting a continuation of the inlet pipe 1 and located beyond the nozzles 2 -2, 'and 5 represents a damper preferably' hinge at 6, and arranged to. open or close, to a greater or less degreethe passage adjacent to the nozzles. This damper has a bracketa which passes through 'a slot inaremovable cap plate 6.. Thisbracket is connected by a link 7 to a piston 8 located'in afdash pot 9. The interior of the dash pot 9ris connec ted by means' of a relatively smallrpipe l0 -with the interior of the supply pipe' 4, said connection with the' dash pot being' above the' piston 8. Y

1l represents weights, for example in the form of disks, mounted upon the link 7 and arranged to prbperly counter-balance the vacuum, or partial vacuum, within the dash ot 9. p In the particular form ofthe invention tively large number of nozzles 2-2 are pro- `creased or diminished at will. u

In practice, the usual throttle may be em.

vided, as seen in Figs. 2 and 4. In the preferred arrangement, these nozzles are arranged vin parallel 'series extending obliquely across the suply pipe. The damper 5 is so arranged that, as it moves to and fro,

' it will vnot only open and close the air pas-v sage from the inlet 1 to the supply p ipe 4,

but it will 'also cut out of the draft of air one or more4 of the nozzles. It will thus be seen Avariable quantity of a uniform mixture of only is the volume of a'ir admitted modiied,

that by the movement of said dampernot but, to a corresponding extent so also is the fuel supply regulated whereby arelatively 1 lliinform mixture of gas and air will be found in pipe 4 to be delivered to the engine according to the demand of the latter. Nowjas to the functionof the dash pot 9.

bviously, as the speed of the engine in- 4 creases and the demand for more fuel in- .creases, a relative increase in vacuum will occur within the supplypipe-4.' This reladuces within the dash pot 9 a correspond tive increase in vacuum 1n said pipe proifngly increased vacuum, by reason of the pipe' connection 10. This moves the piston 8,l

so that, through the medium of the link `7 and bracket 5a, the damper 5 will be opened I to supply additional air and fuel. .In practice, this occurs automatically and with such uniform precision as to provide the much sought for uniformity of mixture in supply pipe 4. To regulate or adjust the action of the dash pot, the weights. 11.-11

ployed whereby a inanual lcontrol may be 'may be in had, but as this constitutes no part of this invention, it is unnecessary to describe it herein.

- It should perhaps be stated that the area of the piston 8 should' be suiiiciently large to permit the partial vacuum within the pipe 4 (transmitted to the cylinder 9) to draw said piston 8 in a direction to' open the damper 5 against the inrush of air tending to close the same.V In the preferable form the area of the piston is so much greater than the crosssectional area of the quires the additionv o 1v1 aforesaid, since this affords one very simple and constant means for regulating the operation Vof the damper controlling means.

Whatl claim. is: y

1. In a vaporizer, an air passagev therein, aplurality of fuel' supply devices arranged in Jv passage `4 that it rethe counter-weights Y said passage, a damper in said passage arranged to open and close the same and also arranged to cut out one or more of said fuel supply devices from or include .the same in the draft through said passage and Ameans controllable by variation in pressure in said passage for moving said damper, said means operating to move said damper to open said passage as the pressure therein decreases and vice versa.

2. In a vaporizer, an air passage, a plurality of separate fuel sprayer tips projecting therein, a damper in said passage arranged to open and cl'ose the same and arranged to cut out one or more tips from, lor include the same in, the intake draft lthrough said passage, means for automatically opening said damper comprising a dash pot open to the atmosphere at one endand a pipe connecting the interior .of said dash pot With said air passage, a piston 1n said dash pot, said piston being connected to said damper' whereby reduction ofpressure in said passage Will be communicated to said dash pot and the piston therein to open said damper.
